"im only a crack in this castle of glass" what band says this in one of there songs its a project for school dont report. im doing a project on music and bands.

linkin park made 'castle of glass'

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
